METAL DISK WHEEL.

Application filed February 7, 1920. Serial No. 356,848.

. new and useful Improvement in Metal Disk lVheels, of which thefollowing is a specification, reference being had therein to theaccompanying drawing.

his invention relates generally to wheels,

and more particularly to a sheet metal disk' wh el, the object being toprovide a wheel body composed of a plurality of sheet metal sectorsermanently or detachably connected toa huh structure, and adapted toreceive a tire carrying rim either directly upon the disk or through themedium of a fixed rim.

Another object of the invention is to provide a sheet metal disk wheelembodying these characteristics which shall be strong,

and durable, and at the same time simple and easy of construction.

Another object is to provide a wheel constructed in the man rhereinbefore described which shall be ideedingly light and one in whichone or mo of the sectors can be removed and replaced in case of damage,and also one in which the disk as a whole can be demounted from the hub.

A still further object is to provide a sheet metal disk wheel which willlend itself to both front and rear hub structures.

With these objects in view, and certain others which will becomeapparent as the description proceeds, the invention consists in thenovel features of construction and in the manner of combinin orarranging them, all of which will be fufiy described hereinafter andset. forth in the appended claims.

In the drawings forming a part of this specification, Fig. 1 is a sideelevation of a portion of a rear wheel constructed in accordance with myinvention, the brake 'drum being also shown in elevation. Fig. 2 is asectional view on the line 22 of Fig. 1. Fig. 3 is a detail perspectiveviewv of one of the sheet metal sectors; and Fig. 4 is a plan view ofthe blank from which said sec tor is made. Fig. 5 is a diagrammatic viewshowing the economical manner of cutting the blanks. Fig. 6 is a detailview showing a slightly modified form of sector. Fig. 7 is a detailview-showinga modified form of fixedrim and means for connecting thetire carrying rim thereto. Fig. 8 is a detail sectional viewof one typeof hub to which the disk sectors are detachably connected. Fig. 9 is adetail view showing the tire carrying rim attached directly toperipheral portions of the disk sector.

In carrying out my invention I employ a" plurality of sheet metalsectors of such shape that when'assembled they will provide a completecircular disk. Each sector A is formed with radial flanges B, and thearouate flange G, and when the sectors are placed together the radialflanges B will provide a series of strengthening ribs for the disk andthe flanges C will provide a circumferential edge or periphery and tothis circumferential edge or periphery I may attach a fixed rim D (Fig.2) also of sheet metal and preferably channeled as shown, the legs ofsaid channeled fixed rim being of different heights, and in practice Iprefer to depress the outer-leg of said fixed rim at definite intervalsas indicated at D. The fixed rim D is intended to receive thereon thedemountable tire-carrying rim E which is preferably formed with aninwardly projecting bead E and also provided with clamping lugs Fthrough which the bolts G pass; and nuts H are arranged upon the ends ofsaid bolts thereby completing the fastening of the demountabletire-carrying rim to the fixed rim, each clamping lug being adapted toengage a depressed portion in the outer leg of the fixed rim. The fixedrim is riveted or otherwise rigidly connected to the circumferentialflanges C as indicated'at I in Figs. 1 and 2. Instead of the channeledfixed rim shown in Fig. 2, I may employ an angled fixed rim D riveted tothe flanges C and carryingbolts G, the demountable rim E having clamps Fwhich fit over the bolt ends and secured bythe nuts H, as-most clearlyshown in Fig. 7. The radial flanges B are preferably made taperingtowards their outer ends as shown in order to give the proper dish tothe disk as a whole and also provide the maximum strength at the pointof attachment to the hub. The hub K is of the usual construction so faras the interior thereof is concerned, but the exterior thereof is formedwith a plurality of bosses L which arebored axially as indicated at Land also split or divided axially as indicated at L Each radial flange Bis upset near the inner end as indicated at B and when two sectors areplaced with their radial flanges together the mating upset or pressedout portions B produce a substantially cylindrical barrel of such sizeas to fit snugly in the axially bored portion L and the portions of theflanges above and below said upset portions will fit into the splitportions L of the hub bosses and the rivets or bolts M are then passedthrough the hub bosses and sector flanges and secured as most clearlyshown in Fig. 2 thereby rigidly connecting the sectors to the hubstructure and it will be noted that the brake drum N can be rigidlyconnected to the wheel body by the same set of bolts or rivets whichconnect the disk sectors to the hub structure, the outer face of thebrake drum being aperture'd to receive the said connecting bolts orrivets. The inner ends of the sector flanges may be tapered or inclinedas indicated at B and the hub is formed with a corresponding inclinationK in order to make a rigid connection between the said flange and spoke.

This type of disk wheel is capable of being employed as a de-mountablewheel and in this event, the disk will be demounted or detached from thehub. This is accomplished by making the bosses L slightly deeper, andhaving the ends of the bores L threaded as shown at L so that the endsof the bolts L can be screwed into the same, and in practice I prefer tobore the bosses on a slight taper and shape the portions B accordinglyso that they can be easily inserted and removed and when clamped inplace by the'bolts will be securely con nected to the hub, but at thesame time easily demounted by removing the bolts.

When the disk is detachably or demountably connected to the hub, thefixed rim or felly may be dispensed with and the tire carryin rim 0attached direct to the peripheral in Fig. 9.

If desired the radial flanges of the sectors may be formed with ribbedportions B which facilitate the welding of said flanges at those points;one sector thus formed being shown in Fig. 6.

A wheel body constructed 'as herein shown and described is light, strongand durable and when painted will have the appearance of a radiallyribbed sheet metal disk, and if desired the ribs can be connected toeach other by spot welding or riveting and with a rigid connection atthe hub and at the periphery an exceptionally strong wheel body will beprovided. A valve stem hole O can be provided in one of the sectorflanges C. In case one or more sectors anges of the sectors, as shownshould become damaged it is obvious that the damaged sector can bequickly and easily removed by withdrawing the rive-ts or bolts andforcing the sector axially outward and the new sector can then besubstituted for the removed sector and secured in place by rivets orbolts as previously described.

Having thus described my invention, what I claim is:

l. A disk wheel composed of a plurality of sheet metal sectors, eachsector having axially extending radial flanges and an axially extendinga-rcuate flange.

2. A disk wheel composed of a plurality of sheet metal sectors, eachsector compris ing an arcuate flange and radial flanges,

all of said flanges being arranged axially and a hub to which saidradial flanges are connected.

A disk wheel composed of a plurality of sheet metal sectors havingradial flanges and a hub having bosses, said bosses being divided, thecontiguous radial flanges of the sheet metal sectors being secured insaid radial bosses of the hub.

4. A disk wheel composed of a plurality of sheet metal sectors havingradial flanges, said radial flanges being upset adjacent their innerends, and a. hub having radial bosses, said bosses being divided andbored, the contiguous flanges of adjacent sectors being in the dividedand bored bosses of the 5. In a Wheel the combination with a hub havingaxially bored and slotted bosses,

of a disk having axially disposed portions adapted to engage saidbored-and slot-ted bosses and means for securing said disk portions tosaid bosses.

6. In a wheel the combination with a hub of a plurality of sheet metalbox-like sectors connected together and constituting a-disk, said diskbeing demoimtably con nected to said hub.

7. In a wheel the combination wit-h a hub having axially extendingbosses of a plurality of sheet metal sectors connected together anddetachably connected to said bosses.

8. A disk wheel composed of a plurality of sheet metal box-like sectorshaving their radial flanges abutting one another, the arcuate flangesforming a support for the rim.

' In testimony whereof I hereunto afiix my signature.
